The 77BF Aluminium Folding Door System is engineered for modern wide-opening entrances where strength, aesthetics, and operational flexibility must work together. With a load capacity of up to 120 kg per panel and a sash height of up to 3.5 m, it suits large, high-ceilinged residential and commercial spaces.

The system supports sash widths of up to 1.2 m and configurations of up to seven panels, with two visual variations for design customization. A bottom roller mechanism provides quiet, smooth opening and closing, while 45 and 90 degree frame installation with press or mechanical corner connections enables fast assembly. Simple or lockable handle options address security requirements.
